ISL22349
Quad Digitally Controlled Potentiometers (XDCP)
Low Noise, Low Power, I2C Bus, 128 Taps,
Wiper Only
The ISL22349 integrates four digitally controlled
potentiometers (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit.
The digitally controlled potentiometers are implemented with
a combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
I2C bus interface. Each potentiometer has an associated
volatile Wiper Register (WR) and a non-volatile Initial Value
Register (IVR) that can be directly written to and read by the
user. The contents of the WR controls the position of the
wiper. At power up the device recalls the contents of the two
DCP’s IVR to the corresponding WRs.
The DCPs can be used as a voltage divider in a wide variety
of applications including control, parameter adjustments, AC
measurement and signal processing.
